Wenjun Ma · Telecom Power Technology · 2012
As one of the most important multiple access of the third generation mobile system,with merits of high bandwidth efficiency;strong security;multiplexed accessed,etc.In the field of mobile communications,the CDMA technology has gotten more and more attention.Focusing on the problem of MAI,this paper discusses and studies the related solutions of MAI.By MATLAB/Simulink simulation platform established,designs and implementes the direct sequence spread spectrum communications signal sending and receiving.Using bit error rate,focusing on comparative analysis of traditional single user detector,decorrelating linear detector and MMSE detector influence on system performance,results show that using decorrelating linear multi-user detection system can achieve good performance.
